    TUHOKlimaticka zmena / Thank you so much for ruining my day


    "Given the sheer enormity of climate change, it’s okay to be depressed, to grieve. But please, don’t stay there too long. Join me in pure, unadulterated, righteous anger."


    "I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act. Once you start to act, the hope is everywhere."

    "Our best scientists tell us insistently that a calamity is unfolding, that the life-support systems of the Earth are being damaged in ways that threaten our survival. Yet in the face of these facts we carry on as usual."

    “We’ve got to stop burning fossil fuels. So many aspects of life depend on fossil fuels, except for music and love and education and happiness. These things, which hardly use fossil fuels, are what we must focus on.”

    A nejde o to, že na to nemáme dostatečné technologie, ty by na řešení použít šly, ale chybí nám vůle a představivost je využít. Zůstáváme při zemi, přemýšlíme až moc rezervovaně. Technologický pokrok to sám o sobě nevyřeší. Problém jsme my, ne technologické nástroje.

    Rostouci hladiny oceanu, zmena atmosferickeho proudeni, zmeny v distribuci srazek a sucha. Zmeny karbonoveho, fosforoveho a dusikoveho cyklu, okyselovani oceanu. Jake jsou bezpecnostni rizika a jake potencialni klady dramatickych zmen fungovani zemskeho systemu?
    Ale take jak funguji masove dezinformacni kampane ropneho prumyslu a boj o verejne mineni na prahu noveho klimatickeho rezimu post-holocenu.

    PER2: U syngasu ujsou do budoucna v zasade 2 moznosti:
    a] plazmove zplynovani odpadu
    b] biotechnologicke
    Oboji s dodatecnem dotovanim patrne vodikem a vodni parou.

    Dokavad nepojedou technologie nasledneho vyuziti syngasu ve velkem, nikdo nepostavi velkou alterrnativni produkci syngasu. Tzn. nejdriv aplikaci syngasu a pak gradientne prejit z fosilu.
    Pocita se zejmena se syntetickymi palivy, ale tam v pripade zpracovani odpadu neni vubec resen problem uhlikove stopy. Naopak jak bych trval na materialove vyuziti ktere setri uhlikovou stopu hned 2x (samozrejmne pokazde s nejakou procentualni efektivitou).

    A.2.2 Global surface temperature has increased faster since 1970 than in any other 50-year period over at least the last 2000 years (high confidence). Temperatures during the most recent decade (2011–2020) exceed those of the most recent multi-century warm period, around 6500 years ago13 [0.2°C to 1°C relative to 1850– 1900] (medium confidence). Prior to that, the next most recent warm period was about 125,000 years ago when the multi-century temperature [0.5°C to 1.5°C relative to 1850–1900] overlaps the observations of the most recent decade (medium confidence). {Cross-Chapter Box 2.1, 2.3, Cross-Section Box TS.1}

    PETER_PAN: Jinak tedka bude probihat nekolik mesicu postupny vydavani zprav, v roce 2022 potom dalsi souhrnej report. Jsem zvedavej, jak se s tim media popasujou. Jestli budou schopny nadraftovat nejaky kompetentni lidi na pokryti. Jsem zvedavej, co komentatori, ktery musej kazdej tejden chudaci generovat nazory na vsechno... Pritom tohle je tema, kde se clovek pro nejakou lepsi orientaci v debatach potrebuje vzdelavat roky.

    The Crisis: Four States of Denial
    … As the IPCC gives it latest report
    The first state of denial is the one everyone is familiar with: that climate change does not exist or, if it does, it is not caused by humans. The vast majority of people are now over this denial (apart from some Republican voters in the US). There is such a thing as facts and, well, facts are facts.
    The second state of denial is that we do not have to engage in an immediate and massive transformation of our economies and societies. There is the pretence for instance that 1.5C is still possible, and that we can stay under 2C by ambling down to “net zero” by 2050. We cannot. As Sir David King the former chief scientific advisor to the UK government has put it “what we do in the next 3-4 years will determine the future of humanity”. This is because the world is already over 500 ppm of CO2 equivalent (the combined effect of all greenhouse gases) and the amount of heat being trapped by the planet has doubled in the last 15 years: “There is no carbon budget left”. Or as Norman Loeb the lead researcher on the heat imbalance research project made clear, we are heading into ecological destruction of unimaginable proportions. The “climate industry” is in denial about this: the diplomats, the political parties, the NGOs, Fridays for a Future, establishment scientists, and the liberal elements in XR. However many individuals in these social networks privately understand the situation perfectly well, but generally only those that are retired speak about it publicly.
    The third state of denial is that we can create this transformation without mass and high level civil resistance. There is massive denial about this even in the supposedly radical elements of the environmental movement. Hence the false compassion that says “you don’t have to get arrested”. The whole of the Left is in denial about this – where is Black Lives Matters, where is the feminist movement, where is the labour movement? They all have the quaint humanist delusion, rooted in their “Enlightenment” philosophy, that nature something separate from society. That’s why Guardian articles only talk about sea level rise, temperature rises, and methane release but hardly ever talk about the secondary social effects of mass slaughter and rape, or genocide and fascism. Covid did not manage to break the denial but climate collapse surely will. The only thing that puts us in the ballpark of effective change given we have no time is economic disruption (closing of ports, motorways, pipelines etc) and/or the mass occupation of the centre of state capitals. Dressing up in costumes, going to ghostly international conferences, and moaning on social media, with all due respect, is just another displacement activity at this stage in the game.
    The fourth state of denial is that the present political system will respond in time to this civil resistance. It will not. Only a political revolution will result in the World War Two transformation we now need. This is not a political statement but a sociological one – conventional political regimes have limits on how fast they can change. And political revolutions will inevitably happen once populations, probably later this decade, come face to face with the truly horrific depth of the fiscal crises and systemic breakdowns we face – given that civilisational collapse is now locked in for large parts of the world. They will demand the removal and prosecution of the political class “who knew all along but did nothing” and institute new political regimes: in other words, there will be revolutions. With a bit of luck they will be nonviolent and involve the institutionalisation of citizens assemblies in northern Europe, Canada and Australia. The US and southern Europe are more likely to descend into civil war, fascistic authoritarianism, and/or social collapse as a secondary effect of hundreds of millions of refugees fleeing from the depopulating sub tropics in an attempt to escape mass starvation and the deadly threat of wet bulb temperatures – Central America, the Middle East, India, and Africa, South West Asia.
    This is where we are in 2021. The “crucial decade” was 2010-20, as we were told at the time, not the 2020’s. The 2020’s will be the decade of consequences. Like the people who understood the real nature of the Nazi project in the 1930’s and took in the Jews during World War Two, those that overcome these states of denial, and act in response to the real nature of the world today, are not predominately part of either the Left or Right, or of a particular religious or cultural group. What they have in common is what Tim Snyder, author of “Black Earth, Holocaust as History and Warning” calls “self knowledge”: the personality structure that is able to overcome the pressure to conform to the herd, and the ethical inability to stand by as society descends into evil.
    In the next two to three years the prevention of humanity’s greatest hell of rape, slaughter, and starvation will depend on whether this small group of people around the world go into active and unlimited nonviolent resistance against the carbon regimes. These people already know who they are.

    Within the next two decades, temperatures are likely to rise by more than 1.5C above pre-industrial levels, breaching the ambition of the 2015 Paris climate agreement, and bringing widespread devastation and extreme weather.
    Only rapid and drastic reductions in greenhouse gases in this decade can prevent such climate breakdown, with every fraction of a degree of further heating likely to compound the accelerating effects, according to the International Panel on Climate Change, the world’s leading authority on climate science.

    Odborníci se už dříve shodli, že klíčovou hranicí ve změnách klimatu je oteplení o 1,5 stupně Celsia ve srovnání s předindustriálním obdobím. Při respektování nejambicióznějšího plánu, který zahrnuje naprosté zastavení jakýchkoliv emisí CO2 a razantní snížení všech ostatních emisí, překonáme tuto teplotní hranici zhruba za 20 let. Teplota se nejprve přehoupne přes hranici oteplení o 1,6 stupně Celsia a poté ke konci století bude klesat na 1,4 stupně Celsia ve srovnání s dobou před průmyslovou revolucí, uvádí zpráva IPCC. Celosvětově se již oteplilo o 1,2 stupně Celsia a lidstvo kritickou hranici nejspíš překoná zhruba o deset let dříve, než vědci původně odhadovali. Panel OSN novou zprávou apeluje na politiky i firmy, aby razantně změnili svůj přístup k výrobě a pojetí ekonomiky, které jsou hlavní příčinou globálního oteplování.
    Bez lidského přičinění by velmi pravděpodobně nenastal žádný z extrémních klimatických jevů posledních let, jako jsou vlny veder na souši i na moři, sucha nebo záplavy. „Je velmi pravděpodobné, že epizody s vydatnými srážkami budou ve většině regionů s dalším globálním oteplováním intenzivnější a častější,“ uvádí se ve zprávě.

    TUHO: Zpráva varuje, že některé zásadní a negativní dlouhodobé změny už nelze ovlivnit. Ať už do budoucna vlády jednotlivých zemí přijmou jakákoliv opatření, budou i nadále tát ledovce, bude pokračovat acidifikace oceánů a stoupat hladina světových vod.

    I přes pesimistický výhled ale zpráva IPCC konstatuje, že je stále reálné dodržet závěry Pařížské dohody z roku 2015, jež si vytkla za cíl nedopustit zvýšení globální teploty do konce století o více než 2°C a pokud možno pouze o 1,5°C. Podmínkou je ovšem omezení celosvětových emisí o polovinu do roku 2030 a dále na tzv. čistou nulu do roku 2050. Nicméně i při zachování globálního oteplení do 1,5°C bude docházet k extrémním a bezprecedentním přírodním katastrofám, varují vědci.

    „Zpráva uvádí, že je nezpochybnitelné, že lidská činnost oteplila atmosféru, oceány i souši a že toto oteplování bude pokračovat dokud budeme do atmosféry vypouštět skleníkové plyny. Je velmi těžké si představit, že by jakýkoliv důvěryhodný vědec toto zpochybňoval,“ řekl pro britskou BBC profesor Tim Palmer z Oxfordské univerzity k nové zprávě o klimatické změně Mezivládního panelu pro změnu klimatu OSN

    @leafwax
    The @IPCC_CH report will be released in the early AM tonight. I helped author it, and tomorrow I'll tweet about some of the findings re: #drought which was one of the things I worked on. In the meantime, it's worthwhile knowing a few things about the process
    1/ IPCC authors like myself do not get paid! We volunteer. It's a three year commitment and it becomes a deep part of your life. Why do we do it? Because we care about making sure the world knows about what has happened and what will happen if we don't cut emissions.
    2/ The text in the IPCC report went through two rounds of public peer review, during which time anyone (I mean anyone!) could read the draft and submit comments. The authors have to respond to *every* comment (there are thousands). #accountability
    3/ The IPCC report doesn't have "new" data. Everything in the report is already published in the scientific literature. The report is an "assessment", which means it synthesizes what is out there and decides how well we understand what has happened/will happen
    4/ As you'll see tomorrow, the report has a lot of parts. Let's break them down. The meat of the report is made up of 12 chapters and an Atlas. Each chapter has a dozen or so main authors and a list of contributing authors. Let me explain the authorship thing...
    5/ The Coordinating Lead Authors (listed first) do what their name implies, they coordinate the production of the chapter, take on a lot of extra admin-style work, and are ultimately responsible for meeting deadlines
    6/ The Lead Authors (like me) do a lot of the writing and figure making. In some cases we are responsible for entire subsections within the chapter. We get help though from the Contributing Authors, who we might ask to draft up a paragraph or two about a specific topic
    7/ Contributing Authors are not officially part of the IPCC process (drafting, reviewing, etc) but are folks in the community who are specialists and helped by contributing some text or sometimes a figure
    8/ Back to the "parts". One step up from the full report is the Technical Summary, which is what it sounds like, a detailed summary of the full report.
    9/ Two steps up from the full report is the Summary for Policymakers, which is probably what you will read tomorrow. This is an even more concise summary, and it has to be approved by governments line by line, which is what has been happening in the last two weeks.
    10/ So in order of shortest to longest, it goes Summary for Policymakers -> Technical Summary -> Full Report. Don't be afraid to read stuff in the full report! There is good stuff that for brevity didn't make it to the top docs!
    11/ Finally, because people are asking about impacts and mitigation, know that the report released tomorrow is just the Working Group I (WGI) report, "The Physical Science Basis". Impacts and mitigation are in WGII and WGIII respectively which are coming out next year
    12/ Hope that helps explain things some! Tomorrow there will be a lot of science to digest. fin/

    “​​It is unequivocal.” Those stark three words are the first in the Intergovernmental Panel on Climate Change’s new report. The climate crisis is unequivocally caused by human activities and is unequivocally affecting every corner of the planet’s land, air and sea already.

    The report, produced by hundreds of the world’s top scientists and signed off by all the world’s governments, concludes that it could get far worse if the slim chance remaining to avert heating above 1.5C is not immediately grasped.
